I am afraid that this is actually damage. It looks like the damage called by the machines that roll coins. Whatever happened, it is not an error.
Damaged. Not a mint error of any kind You need to first find out what you actually have before asking about premiums Edited
If it’s an error you shouldn’t have to put up with that. I’d send it back and insist on my money back.
I think your coin has been spooned, due to the outer edge of all the design letters are facing forward and the edge is a bit wavy in spots. It is allways helpful to post photos of both side of any coin that requires acessment by others..
